Application February 18, 1936, Serial No. 64,475 Renewed August 16, 19394 Claims.

This invention relates to vaporizers of the individual hand type for usein generating vapors for direct inhalation in the treatment of headcolds, catarrh, sinus infection, asthma, hay fever, and otherafflictions of the respiratory organs. The invention is an improvementon the construction shown in my United States Letters Patent #2,197,840,granted Apr. 23, 1940, and among its objects are the reduction ofmanufacturing costs; the provision of simple and improved means foranchoring the switch blades of the vaporizer in place, and the provisionof a combination container and sleeve in which the container, in oneform of my improvement, is relatively shallow and may be used either asa container for the medication to be vaporized or as a support for adiscardable pellet or wafer that contains the medicatlon.

In the drawing,

Figure 1 is a vertical section through my improvement, some of the partsbeing shown in elevation;

Figure 2 is a plan view of the construction shown in Figure 1 with thecap F removed;

Figure 3 is a sectional plan view on approximately the line 33 of Figure1;

Figure 4 is a sectional detail of the bottom of the base A of myimprovement showing a portion of the blade l6, and one of the terminals2| in front elevation;

Figure 5 is a side or edge view of the contact blade I! showing thecurved formation of the lower end l-8 of the blades before they are putin place.

My improvement includes an elongated hollow base A, which is taperedpractically throughout its length. In its lower portion the base isprovided with inwardly projecting lugs or shoulders I, Figure 3, whichare reinforced by upwardly inclined brackets 8. Between these bracketsthe lugs are provided with suitable vertically arranged rectangularsockets or bearings 9 of proper size and depth, as shown. The usualelectric cord B- extends into the base A through the bottom thereof, andis knotted at ill to free its terminals ll of undue strains. Theterminals are suitably anchored to the ends of the strands 12 of thecord and have flat turned back portions l4, and feet or lugs I5 thatextend :at substantially a right angle to a vertical plane. Theterminals are in- 'serted in the sockets 9 and are firmly anchored inplace by vertically extending resilient switch blades l6-I1. The lowerend of each of these blades is normally curved, at I8, Figure 5, thecurve being straightened out as the blades are forced down into thesockets or bearings 9. In this way a considerable amount of springtension and frictiongare produced between the terminals, the blades andthe rear wall of the openings. The friction or tension is of such extentas to firmly 5' but removably secure the blades and the terminals in theassembled position shown in Figure 1, and to prevent the blades movinglaterally or vertically unduly in the bearings '9. To further assureproper lateral positioning of the blades I provide for the blade I! avertically extending groove L9 in the wall of the base A and turn theupper end 20 of the blade into this groove, and l in the case of theblade I6 I turn its upper end 21 abruptly inwardly across the verticalcenter line of the base A and perforate it on this center line toreceive the lower portion 22 of the heater C shown in my aforsaidco-pending application. In the assembled position shown in Figure 1 theprojection 2| of the blade i6 is vertically compressed or deflected toassure constant contact between it and the heater C. It will be notedthat the blades I'6ll lie closely along the inner walls of the base A,and that the blade l6 bears against the base at 23 to form a support forthe blade.

The heater C rests on top of the base A and is anchored to it by the twopiece combination sleeve and receptacle or container D which fitstightly over the upper end of the base and is firmly secured thereon, inliquid tight relation thereto, by crimping or turning the lower edge 24of the sleeve over a shoulder formed for the purpose on the base A. Theupper end 25 of the sleeve is turned over a shallow receptacle 26, theconnection between the receptacle and the sleeve bein liquid tight, andthe bottom of the receptacle being drawn tightly against the upperinsulated face of the heater C by the crimping operation described. Thereceptacle 26 directly receives a 0 medication, when desired, and servesas a support for a medicated, or medicine filled, pellet E of anysuitable construction. I show this pellet in the form of a smallmetallic container having a cover 21 centrally perforated as shown. Asuitable cover or cap F, having a mixing chamber 23, sits loosely downover the combination receptacle and sleeve D, insulates against the'heatof the sleeve, and is provided with a plurality of vertically extendingserrations 29 which at their upper end turn inwardly over the top of thepellet E, similar to the arrangement shown in my aforesaid co-pendingapplication. The construction construction forms, at the bottom of themixing chamber 28, a shoulder that extends over the pellet and serves toposition the cover F on the vaporizer and to retain the pellet in place.

In assembling my invention the cord B is inserted in the base throughthe opening in the latter, the terminals H-l4 being small enough to passthroughthe opening in the bottom of the base. The cord is shovedentirely through the base and is then knotted whereupon it is drawn backto the position shown in Figure 1. The switch button is then inserted,its head 36 oocupying the groove I9. The blades IBI1 are then pressedinto place, after which the heater C is mounted on the upper end of thebase A with its lower portion 22 passing through and engaging theinwardly turned angularly disposed projection 2|. The inclination ofthis projection holdsthe heater oh its seat on the base A until the combination receptacle and sleeve D is set over the heater, and over theupper end of the base A, and is drawn tightly down into place bycrimping its lower edge 24 over a shoulder on the base, as hereinbeforedescribed. This operation serves to draw the sleeve and the container26, firmly into place, straightening out the projection 21 of the blade18 to the horizontal position shown in Figure 1, and pressing the bladetightly in itsgroove in the lug I.

When it is desired to vaporize a medicament I with the preferred form ofmy improvement, the medicament is either placed in the'container or themedicated pellet or wafer E, which is preferably packaged in quantities,is placed in the container or receptacle 26. The switch button 35 isthen pressed in, which throws the upper end .of

,, the blade i7 against the contact washer 36 of the heater Cand lightsthe heater, the thin walls of the pellet E expediting the vaporizationof the medicament. When vapors are produced, the tip 3'8 of the cover Fis placed in the nasal passage, and on inhalation currents of air aredrawn into the vents or ways 29 and are heated as they travel up alongthe hot walls of the sleeve D into the hollow chamber 28 of the cover F.Here the heated currents of air meet and lift the vapors, while hot,into the nasal passage. What I claim is:
